Info On SeaBee units in Pacific and Alutians

Am having major problems researching info on my grandfathers' military career. for some PECULIAR reason each time I request his records ALL i recieve are his Reserve discharge papers. Nothing else! in those papers are mentioned 2 units and a training unit in VA.

My grandfather enlisted in 1942 as soon as his naturalization came thru, in Seattle WA. He enlisted in the SeaBee's (he was a machinist's mate) unfortunately that is about ALL we know for sure. The family thinks that he was in Alaska and in the Philippines. (my mom remembers his sister talking about a trunk he brought back full of things) sadly this was among the things lost in a fire, including the only picture she knew of -of him in uniform.

I have had very little luck finding ANYTHING in detail on Seabee units let alone the 2 units i have. the other odd thing I noticed in what few pages I have recieved was the 2 units mentioned >>cbd 1050 and cbd 1051 history started in 1944 but he enlisted in 1942 and there seems to be a gap in what little info i have.

I would appreciate any ideas or information on how to find more info on my grandfather, his units that he served in,- where he might have served, or on the SeaBee's themselves. thank you
